  • Applications

    Diisononyl adipate (CAS 33703-08-1) is a non-phthalate plasticizer used to soften PVC and other polymers, providing flexibility and processability in polymer formulations. Common applications include plasticizing PVC for cables and flexible films; serving as a plasticizer in coatings and inks to improve film formation and flexibility; used in adhesives and sealants to enhance elasticity; employed in construction materials and vinyl flooring to impart softness; and used in automotive interiors and other consumer plastic parts to improve the flexibility of polymer components.
